How to Unlock Car Door when Keys are inside Car

Easy way to unlock your car.
To All You Forgetful People (and there are a lot of us!)
This only applies to cars that can be unlocked by that remote button on your key ring. Should you accidentally lock your keys in the car and the spare keys are home, and you don't have "OnStar," here's the answer to the problem !

If someone has access to the spare remote at your home, call them on your cell phone (or borrow one from someone if the cell phone is locked in the car too!)
Hold the cell phone about a foot from your car door and have the other person at your home press the unlock button, holding it near the phone.
Your car will unlock. I tried it and it works. Saves someone from having to drive your keys to you.
Distance is no object. You could be hundreds of miles away but if you can reach someone who has the other "remote" for your car, then you can unlock the doors (or the trunk, or have the "horn" signal go off, or whatever !)

Very interesting.
I wonder what is the bandwidth allowable thru the GSM phone. May be some of us from communication industry can gives us more info on this.

Technically speaking, the logical step to squeeze into the digital packets, switching station will first cut-out the needed voice info to something like 4kHz bandwidth (human ears full bandwidth is 20hz - 20khz). And that 's why our voice sound a bit funny over the phone. And at what frequency the remote-alarm works? I don't think it's within our ears/voice bandwidth.

That makes this trick a bit suspect, however there's no harm in trying.
